Impact on mining hazards

1. MITIGATION OF MINING
HARARDS

2. WHAT IS MINING GEOLOGY ?
2
Mining geology is an applied science which combines
the principles of economic geology and mining
engineering to the development of a defined mineral
resource.

4. Let’s start with the first set of slides
4
Mining geologists and
engineers work

5. Mining geologists and engineers work to
develop an identified ore deposit to
economically extract the ore. Mining
geology is the process of exploration and
exploitation of ore or economic minerals
from the earth..

6. Impact on mining
 Respiratory hazards .
 Accidental explosion due to adopting
unsafe practices.
 Noise and vibration .
 Mine water discharge and erosion, etc.
 Physical hazards.

7. Respiratory hazard
The problem ,primarily due to dust inhalation,
exposure to silica dust may cause silicosis.
Inhalation of toxic gases released during mining
causes health related problems.

8. Measures of respiratory hazards
8
 Excavators, dumpers, dozers, drills other
automated equipments will be enclosed.
 Use of personal breathing protection will be
made compulsory .
 Spraying with water on all working faces & haul
roads, by special spraying machines or water-
sprinkler.
 Regular health monitoring of workers.

9. Accidental explosor
All activities involving storage, handling and transportation
blasting operations will be safe under the supervision of qualified
Mines Manager. Risk of explosives is proposed a specific disaster
management plan to minimize the risks.

10. Measutres of accidental explosives
10
 Rules made
under the
Indian
Explosive Act
and conducted
with proper
licence and
approval of
authorities
 Non-electric
shock tube
initiation
systems will
be deployed to
enhance
safety of
operations,
better blasting
control and
reduce noise
due to air
blast.
 Sufficient fire
extinguishers
will be
installed at
selected
locations

11. Noise and vibration.
11
12.4% –25.7% mining workforce are suffering from
noise-induced hearing loss in India.o
m70.2–81.5 dB-noise level, noise levels in more than
50% of the samples exceeded 90 dB(A). noise-induced
hearing loss in India.

12. Mitigating measures
12
i. Use of Diamond wire saw cutting as
given in the Mining Plan,
ii. Chemical blasting and
iii. Direct fact cutting equipment

13. Water in mines
Sudden rush of water due to heavy rain and
flooding cause major damage to the men and
machineries engaged.
 At the high turbid slurry water coarse and
sand filtration settling tank may be arranged to
filter water before discharge into natural
systempit bottom.
13

14. Physical harards
 Specific personnel training on work-site safety
management.
 Work site assessment will be done by rock scaling
of each surface exposed to workers.
 Maintenance of yards, roads and footpaths,
providing sufficient water drainage and
preventing slippery surfaces with an all-weather
surface.
